5. Turn off wireless when reception is poor.
5. 信号弱的时候关闭无线网络
You may have noticed that when you’re in a place without good Wi-Fi or cellular coverage, your phone’s battery seems to drain much more quickly. That’s because the phone uses energy searching for a good signal and, if the signal is very weak, trying to get a better connection.
你可能注意到了，在Wi-Fi或蜂窝网络覆盖不好的地方，手机电量耗得特别快。这是因为手机会使用电能寻找耗得信号，如果信号特别弱，还要试着更好地去连接。
